Experimental and Simulation Study of an Auxiliary Circuit to Improve Gain of the Quantum Flux Parametron

概要

論文の詳細を見る
The gain of parametron-type devices like the Quantum Flux Parametron (QFP) is reduced by non-uniformity which causes an apparent input bias. A method to improve gain by circuit design is considered. A booster, a dc-activated QFP attached to the output of a clock-activated QFP, improves gain by doubling total output current without significantly increasing minimum input current. The booster's operation is analyzed theoretically from its quasi-static behavior and compared to results obtained from low-speed experiments on fabricated test circuits and computer simulations at high-clock rates.
